The Cantonal Association of Zurich Electrical Installation Companies (KZEI) is responsible for the Elektro-B BildungsZzentrum EBZ in Effretikon. Members of the association are electrical and telematics installation companies.

In 1972, the new Electrician Training Center (ELAZ) was put into operation. Around 1000 electrician trainees began attending the new introductory courses. Just one year later, they were joined by electrical draughtsmen.

In just a few years, the number rose to over 2,000 apprentices. The new professions of assembly electrician and telematics technician were integrated into the course program in 2000. The former introductory courses are now called inter-company courses (üK).

In 1990, the General Assembly decided to further expand the course rooms and add the area of further training (WB) to the program. 700 to 900 entrepreneurs and professionals from the electrical installation trade attend the further training courses every year.

In 2001, the Elektro-Bildungs-Zentrum was awarded EduQua certification.
